I i I DESCRIPTION OF THE ILLUSTRATIVE EMBODIMENTS Referring now to the drawings, the support bracket embodyingsome of the principles of thepresent invention'is shown in FIG. I and is generally represented by the reference-numeral 1 0. The bracket 10 consists of an elongated channel member of electrically. nonconductingmaterial 11 and is utilized for attaching an elongated element such as a pipe P or a plurality of pipes with a securing means 40 in communion with V grooves 30 which provide element receiving recessess. These recessess are incrementally spaced perpendicular tothe longitudinalaxis of the channel 11.

InQthis particular embodiment which may more clearly-be seen in- FIGS. 2 and 3, which are detailed section views of FIG. 1, it might be desirable to reinforce the channel 11 with an existing metal channel member which is generally U-shaped and has depending flanges 15' which coincide with shoulder members 27 on the channel member 11, said shoulder members thereby slidablyengage the channel '11. The outer support channel 14 now encompasses a portion of the securing channel 11 and after the channels have been adjusted relative to their desired positions, relative to each other, the channel member 11 is secured by fasteners 29. The channel 11 is provided with internally threaded apertures 28 which are bi-directionally perpendicular to each other and equi-distantly spaced in pairs perpendicular to the longitudinal place of the axis of the channel 11. These internally threaded apertures 28 receive an externally threaded fastener 29 which is provided at one end with an inset hexagonal aperture, this fastener is commonly known as an allen head stud. These studs 29 are threaded through the apertures 28 into frictional engagement with the inner surface of the outer channel bias shoulder members 27 into engagement with the depending flanges on the channel 14. I

As shown in FIG. 1 and in more detail in FIG. 3, a portion of the channel member 14 is left to overlap the nut 41 to rotate due to the dimension of the channel in relation to the-nut. v I As shown in FIG. 4, the size of the V-groove associated with angularly disposed surface 21 is of a slightly -member l4 and thereby forces the channel upward to-v ends of the support channel member 11 and thereby 'presentsa surface for an aperture l6'to receive a threaded hanger rod 17 with nuts 18 to sandwich a portion of channel14 into position on the rod 17. The rods then are fixedto a fixed structural support 19, and to I those skilled in the art, this is known as a trapeze type arrangement for suspending .pipes in a building construction. It will be obvious that'while hanger rods have been shown, a simpler but less rigid means for securing the bracket assembly could be accomplished by simply using hanger wires, bent and twisted to accomplish the same effect. t v

As more clearlyseen in FlG. 2, the channel member 11 has angularly disposed sides 21, 22, 23 and 24. Each' side is fitted with V-grooves 30'which are spaced incrementally along a given surface perpendicular to the longitudinal axis of the channel. These grooves present element receiving recesses 'to receive an elongated element .such as a pipe P. By virtue of the incremental spacing of these grooves 30, which may be for instance 1 inch. apart from dead center to deadcenter, it pro-' vides a measurement guide to an installer whereby he can cut alengthof channel to a specific length without the-necessity of measuring tools.

Running parallel and down the center of the base support channel are receiving channels 26 which have a width and depth sufficient to receive the threaded leg portions 42 of a securing meansgenerally indicated by the reference numeral 40. Said receiving channels 26 act in concert with the clamping means which is generally U-shaped with leg portions 42 terminating in threads at their lower end toreceive huts 41 which are provided to act as retaining shoulders for the securing means when inserted into the receiving channel 26. The receiving channel'26 receives the nut 41 and a portion of the threaded leg portion 42. The nut 41 is biased up, within the receiving channel 26, into engagement with receiving shoulders 27 of the channel 26.

The said biasing of the nut 41 into engagement with the receiving shoulders 27 is enacted by means of a butterfly type bolt 44 located at the apex base portion of the-securing means. This apex portion 43 of the securing means 40 is curved and-encompasses a portion of the pipe P. When the clamping means 44 is threaded into abutment with the pipe, it thereby depresses the pipe into engagement with grooves 30 and simultaneously lifts nuts 41 into engagement with the receiving shoulders 27. It should be noted that the width of the receiving channel 26 is such that it will not permit the smaller size thanthe grooves on the surface 22 which,

in turn, are of a different dimension from those grooves on surface 23 and thus differentfrom those grooves on surface 24. The reason for the differentsize V-grooves 30 is to make the channel member 11 universal, in that it will be capable of receiving a plurality of size ranges of pipe to correspond with a compatible recess.

' Shown also in the receiving channel 26 is'an' annular cutout 12 which would allow the nut 41 on the securing means 40 to be inserted by dropping one bolted leg vertically down into the channel and sliding the securing means with one bolted leg in the channel until the-other bolt on the complementary leg coincides with the annular cutout l2 and is dropped into place. At this point the securing means can then be slid along the channel to its desired location for clamping. The annular cutouts thereby allow vertical access in a number of places along the channel without having to rely upon entrance from oneor the other open ends on the channel, which may not be accessible without greater difficulty, if a securing means and pipe have already been clamped Briefly referring back to FIG. 5, it will be seen that the receiving channels 26 extending into the. channel 11 from each of the said angularly disposed sides 21, 22, 23 and 24 form a reduced cross-sectional area within support channel 11', primarily between one receiving channel and its corresponding juxtaposed receiving channel producing a break-offplane within,

and rendering 'the channel easily divisible with a saw or other suitable cutting tool. 1

Referring now to FIG.7, it will be seen-that two support channels 11 have been divided in this fashion forming half channels 11 and their elementreceiving recesses or V-grooves 30 have been placed in juxtaposition relative to each other to sandwich therebetween the pipes P. The channels 11' themselves thereby secure the pipes threading the fastening stud 29 from one threaded aperture 28 in one-half of one channel member 11' into corresponding threaded aperture 28 into the other complementary half of another channel member 11'. A threaded end portion of the stud projects from the channel member allowing it to be fixed to a plate 32'on a fixed structural support 33' by threading nut 34' onto the end of the between plate 32'.

It will now be seen in FIG. 8, that pipes P have been suspended in the same manner as shown in FIG. 1 in a trapeze type arrangement In this embodiment, theindividual securing means 40, shown in FIG. 1, iseliminated and the half channel member 11 is threaded through studs 29 selectively along the channel to en{ gage the lower full support channel 11. The upper complementary half channel 11' and lower-full channel 11 stud 29 sandwiching thereadetailedillustration shown in FIG. 9.

.- sandwich and clamp therebetween the pipes'P. The principles of the embodiment are more clearly seen in FIG. a is .an alternate embodiment of the support channel 111 having angularly disposedsides 121, 122,

123 and 124, with receiving channels 126 running centrally and in a parallel plane with the axis of the channel means 141 is thereby internally'to bethreaded to the threaded'ends of the securing member-140. Said secur ing member 141 has a pair of upstanding flanges 144' I26. Thereceiving channel is provided also with a recessed groove or.slot 129 which is formed with and runs centrally along the bottom of the receiving'chanto engage a recessed portion l27.in receiving channel nel 126. This groove 129. is provided to further reduce I the cross-sectional area of thechannel ll 1 from receiv-' ing channel 126 to its juxtaposed receiving channel on the opposite'an gularly disposed side. The slot 129 is provided also as a guide for a cutting tool to allow easy separation of the channel into divisible parts.

FIG. 11, which is a top plan view of a portion of FIG.

10, shows a rectangular. cutoutl12 in the shoulder 127 of the'receivingchannel 126. This cutout 112 is com ing means 141. The cutouts are provided in spaced pluv rality along each receiving channel 126 to'allow vertical access of member 141 on securing element 140 so as to allow a pipe Ptobe inserted in a number of places along the channel withouthaving to rely uponinsertion from one'or theother open ends of the channel.

Shown also in FIG. 11 is another alternate means for fixing a length of. one support channel member'lll to the ends of another channel member. Each channel 111 will have at one end, a fixed stud member or dowel I plementary in shape and slightlylarger than the retain I without departing from the spirit ofthe' invention which 4 pin l36'and at its opposite end recessed cylindrical ap- I ertures 135 complementaryinsize and location to receive said dowel pins 136 molded into the opposite end. When fixing channel 111 to an additional length" of channel, these apertures and complementary dowel pins act as aligning means; and, if suitable adhesive is applied to the abutting ends of the channels and their associated dowel pins, a structurally sound joint is formed and therein bonds the members.

In FIG. 12 is shown the channel member 1110f FIG. 10 with an alternate securing means to communicate and lockingly engage receiving channel '126. More clearly shown in the exploded perspective view of FIG.

13, the alternate securing means 240 is generally a worm gear drive type securing and clamping means. Said clamp consists of a pair of bands 242 which at 2" their upper base end are passinglyaligned and drivingly positioned relative to each other by virtue of housing 245, inside of whichthere is a worm gear 247 provided with a screw head to turn the worm. The worm engages notches or' slots 246 on the bands 242 to tighten or loosen retaining members 241" located on the terminal ends of the bands. Said members 241 are provided with upstanding flanged shoulders 244 to thereby lockingly engage recessed receiving shoulders 127' within the receivingchannel 126 on the supportchannel "111. By

tumingthe screw head on theworm 247 to bring the bands toward each other, it will thereby 'redu cethe cross-sectional area of the securing means and bring a peripheral surface of pipe P into locking engagement with V-groove 130 on thesupport'channel', while at the v same time urge flanges 244 into engagement with complementary shoulders l27. on the receiving channel 126 of the, channel .111. I v

As shown in FIGS. 14 and 15, a still further embodiment of the support channel is designated generally by the reference numeral 311. Said channel has angularly disposed sides 321, 322, 323 and 324. Each angularly disposed side is provided with a receiving channel 326.

Said'receiving channel 326 is provided with ratchet type teeth '327 which provide shoulders to engage complementary ratchet teeth 344 which provide retaining means on the securing element 340. Securing means 340 is substantially U-shaped with an arcuate base' member 343 terminating in straight legs 324 which are provided withratchetteeth 344. At the apex of the base member 343 there is provided a butterfly'screw" 345 to further clamp the pipe into engagement with recess 330, once the securing means 340 has been forced into engagement with the receiving channel 326. 'At the bottom of the receiving channel 326. is provided a groove orslot 329 that runs longitudinally and paralleldown the center of. the receiving channel 326, which servesto further reduce the cross-sectional area from one chann'el326 to its opposite corresponding channel thus rendering it more easily divisible and defining a cutting guide for a suitable cutting tool.

It has now become apparent that the above described illustrative embodiments of a pipe'supporting bracket are capable of obtaining the above stated objects and advantages.
